OIL-FILTER.

SPECIFICATION forming part of Letters Patent No. 7 32,6 59, dated June30, 1903.

Application filed October 2, 1902. Serial No. 125.705. (No model.) Y

To all whom t may concern.:

Be it known that l, BEnXToN L. SCOTT, a citizen of the United States',residing at "Washington, in the District of Columbia, have invented newand useful Improvements in Oil- Filters, of which the following is aspecification.

My invention relates to certain new and usevful improvements inoil-filters, and has for its object to provide a filter which shall besim-` ple in construction and operation, which may be readily takenapart for the purpose of cleaning, and in the use of which the oil willbe rapidly and, thoroughly cleansed from impurities.

With these objects in view the invention resides in the novelconstruction, combination,

and arrangement of parts hereinafter described, and particularly pointedout in the claim. In order that my invention may be clearly understood,I have illustrated the same in the accompanying drawing, in which thefigure is a central vertical section of a iilter constructed accordingto my invention.

Referring to the drawing, 1 indicates the outer containing-tank having,as usual, drawo cocks 2 and 2EL and a gage 3. Within the tank 1 is areceptacle 4, having a downwardlycurved upper-edge portion 5, by meansof which it is supported from the upper edge of the tank l. Thereceptacle 4 tapers slightly from top to bottom and has about the depthrelative to the tank 1, as shown. The bottom of this receptacle is openexcept for a narrow inwardlyextending annular flange 6. Upon this liangeis supported a second receptacle, 7, which for the purpose is providedat its upper edge With a similar outward-extending flange'S. Saidreceptacle 7 also tapers from top tobottom, is of slightly less depththan the receptacle 4, and is provided in the bottom with an outlet 9,through which the oil may ilow down into the tank l, whence it isWithdrawn through the draw-off cock 2. Each of the receptacles 4 7 isprovided on its inner side near the top With handles `10 11,respectively, and at a suitable point above the bottom the receptacle 7is provided with cleats 12. Four or more of these cleats may beemployed. These cleats are for support- Vtank l.

ing a disk 14 of open-work fabric, such as woven wire, which isremovably seated upon` said cleats. A similar disk 15 is removablyseated upon the flange 8 ofthe vessel 7. Each of said disks 14 15 isadapted to support a sack of bone-black 16 17, which sacks are of coursecircular in shape and of a size to fit snugly within the respectivereceptacles 4 7. In the upper receptacle "4 at a suitable distance abovethe sack of bone-black 16 is located a circular plate 13,havingperforations 18, said plate being supported upon cleats 19, uponwhich it is removably seated, and having a handle 20, by which it may belifted out of the receptacle 4. The tank 1 is provided with a cover 21,having a handle 22.

In operation oil ,is poured into the receptacle 4 upon the plate .'13,which being perforated throughout acts Aas a baffle-plate to distributethe oil and cause it to fall over the entire surface of the upper sack16 of boneblack. The oil percolates through this filtering medium andthrough` the disk 15 and falls upon the lower sack 17 of boneblack.Percolating through the `bone-black in this latter and through the disk14 it passes out through the outlet 9 and falls to` the bottom of the Inpassing through the two sacks of bone-black the oil will be thoroughlycleansed from all impurities and when drawn from the tank 1 may at oncebe used again.

This filter is intended more especially for use in po wer-houses andsimilar places where hundreds of gallons of oil are used daily forlubricating the machinery, the oil after use being collected and passedthrough the filter to remove from the oil all grit and impuri` ties, sothat the same oil may be used over and over again. The salient featureof the invention, however, is the facility it affords for the readyremoval and replacing of the therein,no mechanism-such as bolts, screws,or the likebeing required for securing any of the parts in position. AsWill be apparent from the drawing Without further. detailedliilteringt-receptacles and the parts supported IOO boiled or otherwisetreated to remove grease and impurities therefrom which have beenabsorbed or Collected by the bone-black in the filtering operation.

Ofeourse I do not limit the invention to the use of bone-black as afiltering medium, as any other suitable substance may be employed inlieu thereof.

Having thus fully described my invention, what I claim as new. is-

In an oil-filter, in combination with an outer tank, a receptacle havingan upper curved edge portion in engagement With the upper edge of saidtank and having an open bottom provided With an inwardly-extendingflange, a second receptacle having a flanged upper edge and supportedtherebyfrom the bottom BRAXTON L. SCOTT.
